PATENT FFICE.

SIDNEY D. KING, OF MIDDLETOWN, NEW YORK.

IMPROVEMENT IN DUMPING-CARS.

Specification forming part of Letters Patent No. 119,856, dated October10,1871.

To all whom it may concern:

Be it known that I, SIDNEY D. KING, of Middletown, in the county ofOswego and State of New York, have invented a new and valuableImprovement in Dumping-Cars; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makinga part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawing is a side View of my invention. Fig. 2 is a rearview, and Fig. 3 is a partial bottom view of the same.

The nature of my invention consists in the novel construction andarrangement of a dumpin g-car, which moves past the centre to disch argeits contents, as will be hereinafter fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing.

In the accompanying drawing illustrating this invention, A represents aturn-tableprovided on its upper side with two longitudinal inclinedguides or ways, B, and said guides are provided with grooves b uponwhich the box-platform C moves. The platform C is held in properposition for loading by means of .a spring-hook, d, secured on the underside of the boxD, and which catches on a spring-bar, e, on the underside of the platform. The projection e is securely fastened to the underside of the platform and adjusted in place by means of a spring, f, asshown on the drawing in Fig. 3. The hook el' is released or unlatchedfrom position bythe stop K secured on the upper side of the turn-table.E represents a carrying and dumping-box, constructed with an open topand having' aixed to the outer sides pulleys F. The box is hinged uponthe beam H on platform O, the beam and box being so arranged that thebox is hinged at or near its center, and that the beam will passdirectly over the centre of the turn-table. The box D when in properposition rests upon a support, I, on front of the platform C, and isheld down by the spring-hook d projecting from its under side andpassing through a hole in the platform, where it is caught and held byaspringbar, e. One end of this spring-bar has an arm, K", which passesdownward a short distance on the under side of the platform. When theplatform O passes down the incline planes B so that the box will passbeyond the center, the end of the bar e strikes the stop K', whichreleases the latch or hook d, and the box becomes inclined. M representsadjustable hooks secured to the upper surface of the transverse-bar o onthe turntable. One end of the chain N is affixed to this adjustablehook, as shown in Fig. l. The chain N is affixed to the dumping-box gateIt at n, and, passing over the pulleys F to the adjustable hook M,serves to aid in adjusting the gate while the dumping process is carriedon. The gate R is hinged to the rear end of the box E, and is providedwith side-boards or guides S, as represented on the drawing. The letteru designates pins or stops affixed to the sides of the box, as

shown, and intended for stopping the gate inthe dumping process.

W represents a hand-screw adapted to operate in the female screw X. Theparts are respectively attached to the upper surface of the turn-tableand to the inner side of the sliding platform, and operated by means ofthe hand-wheel Z. By this means the sliding platform and box are gradually moved outward until the spring-hook d engages with the stop K',which releases the hook and the load of the box is carefully discharged.

I claim as my invention- 1. rlhe combination, with a sliding dumpingcarprovided with the pulleys F and the adjustable plates m, of theautomatic gate R, and the connecting' chains N, substantially 'asspecified.

2. The combination, with the sliding platform C, of the hinged car bodyD, and the motivescrew W working in the female screw X, substantially asspecied.

In testimony that I claim the above I have hereunto subscribed my namein the presence of Witnesses CHAs. L. HORTON,

F. B. DENTON. (121)
